我在 Phone 身份验证系统中没有收到来自 firebase 的 Otp

Question

我基本上创建了2个Xml。用户输入 phone 号码，然后按下按钮进入 OTP 验证屏幕。但这里的问题是我没有收到来自 Firebase 的任何 OTP，但 5 秒后我收到一条消息，提示验证失败。如果我什至没有收到消息，它怎么会失败。我还尝试输入另一个数字，以便我可以手动输入代码。但是 Firebase 没有向我发送 OTP。

基本实现---点击忘记密码->询问手机号码->验证OTP->重置密码->登录页面

P.S 我在 Firebase 中启用了 phone 身份验证。

OtpActivity.java

public class VerifyOtp extends AppCompatActivity {

    public String NumberEnteredByUser,verificationCodeBySystem;
    Button VerifyButton;
    PinView phoneEnteredByUser;
    FirebaseAuth auth;
    PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallback;



    

    @RequiresApi(api = Build.VERSION_CODES.N)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_verify_otp);
        getSupportActionBar().hide();

        Intent intent =getIntent();
        NumberEnteredByUser = intent.getStringExtra("phoneNo");



        VerifyButton = findViewById(R.id.btnVerify);
        phoneEnteredByUser = findViewById(R.id.EnterCode);
        auth = FirebaseAuth.getInstance();

        send_code_to_user(NumberEnteredByUser);




        VerifyButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                checkcode();

    }

                }
                else {
                    Toast.makeText(VerifyOtp.this,task.getException().getMessage(), Toast.LENGTH_SHORT).show();
                }

                        .setActivity(this)                 // Activity (for callback binding)

                        })          // OnVerificationStateChangedCallbacks
                        .build();
        PhoneAuthProvider.verifyPhoneNumber(options);

    }
}

构建Gradle项目

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath 'com.google.gms:google-services:4.3.8'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

构建Gradle应用程序

请帮帮我。谢谢！！！

Answer 1

在用户 phone 号码前添加国家代码（印度为 +91）。它会起作用。

NumberEnteredByUser = "91"+intent.getStringExtra("phoneNo");

Answer 2

验证失败，因为您没有启用应用验证。为此，您可以按照以下步骤操作：

转到 Google Cloud Console，Select 您的项目并启用 Android 设备验证。这里直接link：https://console.cloud.google.com/apis/library/androidcheck.googleapis.com
在Android工作室中，转到右上角栏，然后按“Gradle”。然后展开（您的项目名称）> app > Tasks > android，然后双击 signingReport。您将在运行 window 中找到 SHA1 和 SHA-256，如下所示：
转到您的 firebase 控制台，然后打开应用程序。转到项目设置。向下滚动，您会发现 Add Fingerprint，您需要在其中插入 SHA1 和 SHA-256 密钥。插入后，您需要下载更新的google-services.json。将 android 工作室项目中的旧 google-services.json 替换为新的。
现在在app级添加浏览器依赖，因为app需要从浏览器打开验证码页面：
```
 implementation 'androidx.browser:browser:1.3.0' 
```
然后，在 Android Studio 顶部菜单 Build > Clean Project 和 Build > Rebuild Project

现在，你可以开始了。

注意：您的应用可能会显示验证码验证网页
